8 items in the Thuztra Learn library carry the topic quant roles: 7 reference articles and 1 puzzle. They are gathered here so one idea can be met in every form it takes, which is usually the difference between recognising a term and being able to use it.
8 of them have pages of their own, linked below. Everything else is listed with the summary its author wrote. The one problem on this topic is set out under its own heading and quoted in full.
Problems in full
Quoted exactly as the library sets them, so the topic is something you can try rather than something you have read about.
Here is one written rule. On any day, take the average of the last five daily
numbers and the average of the last twenty. If the five-day average is above the
twenty-day one, hold one unit of the thing. Otherwise hold nothing.
Somebody walks that rule down a long stretch of past numbers, which is something
called a Backtest, and reports that it came out 60 points above where it
started. Four people then say four things about that report.
- A. "Forty other rules were tried on this same stretch before this one was kept."
- B. "On the days the rule turned on, only about a third of the amount wanted was
there to buy at anything near that number."
- C. "The twenty-day average in the test was taken over calendar days. The thing
that would run day to day takes it over days the market opened. Those are not the
same twenty days."
- D. "One unit is more than this account could carry on its worst day in the
stretch. Half a unit."
Three questions.
- Which of the four quant desks does each of A, B, C and D belong to?
- What has the 60 established, and what has it not?
- D's objection is accepted and the amount held is halved. Somebody says: fine,
the 60 becomes 30, and the rule still works. Name what is wrong with that
sentence, and there is more than one thing.

Puzzles
A rule, one number out of a test of it, and four people who each object to that number differently. Sort the objections by whose job they are, then price what the number claims.
